Performance tweak for samples/display, resulting in a much faster
application start, particularly when built in debug mode, when Windows
messages are dumped to the system debug channel for
inspection/diagnosis.
Speed up the Append() loop below by foregoing the repeated resizing of
the choice drop-down via repeated calls to GetBestSize() which happens
deep inside the Append() call chain and executes another inner loop
calling SendMessage() to get the control contents. (This exhibits
1/2*O(N^2) behaviour thanks to the linear growth of the length of the
inner loop to the length of the outer loop (= number of items to add),
while it is re-executed for every new added item.)
With the 'display' sample, that's about 500+ rounds and about 500*500/2
SendMessage() calls less now on my dev/test rig, taking noticeable time
to start the display application.
---
Issue was found due to the barrage of '(winmsg)' Windows Message debug
log lines zipping by in the monitor app when the sample was build in
Debug Mode. Only significant difference with the Release Build is those
debug lines being output, hence the performance gain is less, but still
measurable, in a Release build. When the machine is otherwise severely
loaded (UI render core maxing out), "measurable" becomes "obnoxiously
noticeable" again on Win10/64.
Closes#22049.
wxEVT_DISPLAY_CHANGED notifies not only about the change of resolution
of a display, but also about removal or addition of a new display, so we
need to completely repopulate the notebook showing the displays on
receiving it.
While this is not done for all the ports yet, the new API allows
returning different PPI values for different monitors, unlike the old
(and still existing, but implemented in terms of the new one) global
function.
Allow getting the depth of any display, not just the primary one, even
though this is not implemented for Unix ports currently.
Mostly do this for consistency with the other display-related functions.
Added EnableFullScreenView() to have a full screen button in the title bar and also allowing ShowFullScreen() to make use of the newer full screen API.
See #14357.

This keyword is not expanded by Git which means it's not replaced with the
correct revision value in the releases made using git-based scripts and it's
confusing to have lines with unexpanded "$Id$" in the released files. As
expanding them with Git is not that simple (it could be done with git archive
and export-subst attribute) and there are not many benefits in having them in
the first place, just remove all these lines.
If nothing else, this will make an eventual transition to Git simpler.
Closes#14487.

Add a special symbol which is defined only if the icons and other images (e.g.
cursor) are in the separate resource files and don't need to be embedded as
XPMs in the main program.
This makes the checks more clear and more customizable as it's enough to
change wxHAS_IMAGES_IN_RESOURCES definition instead of changing many platform
checks.

MS and Apple guidelines mention ellipses should generally be used when a command needs additional information from the user before the operation can execute. This is not the case for showing an about dialog so the ellipses have been removed.
